The difference between 2D plane marking and 3D marking
Flat engraving is performed on a flat surface, typically using single-line, intaglio, or relief engraving techniques, with the lines or patterns remaining in the same plane. Curved surface engraving involves creating three-dimensional forms (such as relief) on curved surfaces or with concave and convex surfaces. The curvature and depth of the curve must be considered to create a three-dimensional effect.
3D marking machines are more suitable for workpieces with complex shapes. They can engrave flat, curved, stepped, and irregular surfaces. Dynamic focus allows for different heights, preventing blurred markings at the edges of curved surfaces due to defocus. Even on objects with uneven surfaces, the marking effect is uniform.
Curved surfaces typically include: a cylinder (the side of a cylinder is a curved surface), a sphere, a cone, a torus, a hyperbola, and a parabola.
